We use 46-0-0 for our winterizer app spread with our Z-spray. We have had no issues, in fact everyone boasts about the deep/early greenup in the Spring. I do pour over an additional screen when loading just as a precaution because with the spreader turned down this low I want to eliminate the tendency to clog easier.
The added amount of white particles makes up for spreading less material (to the eye.) Basically it still looks like you're spreading slot because it's straight nitrogen. I've never had a customer ask how much stuff I'm putting down. Besides, , they don't pay for fert, they pay for results.Posted via Mobile Device
